Dear GroupDIY,
having hard time to find a easy to follow tutorial on measuring EIN of a
recorder.
So far I gathered this:
– measuring 150 ohm resistor (between 2 and 3 pin on XLR) seems to be a standard
– measuring should be done at highest possible preamp gain (seems like
recorders offer best results at that point)
– results should be constrained to a specific bandwidth of interest
(e.g. 20 Hz – 20kHz)
My question is – how to get from a bandwidth limited recording of a
150 ohm to the final EIN level?
Here is a list of “home-measured” recorders that inspired me:

Thank you very much,
Jonas
